Title: Improvements in Electric Protection Devices.
Filed: 1902-06-24
Granted: 1903-05-14
Abstract: 14,295. Lake, H. H., [General Electric Co.]. June 24. Cut-outs; switches.- Relates to a protecting- means specially adapted for constant-current circuits. The circuit from a constant-current transformer 5 contains lamps 10, 11 arranged in series, a switch 14, and automatic devices for short-circuiting the secondary of the transformer when either the potential is too great or the current excessive. The circuit passes round an electromagnet 18 which operates, when the current becomes excessive, a lever 19 engaging a lever 20 formed with a catch 16 which normally holds a shunt switch 15, 17 out of action. The lever 20 is also connected by a link 27 and adjustable nut 28 to a lever 26 connected to a spring 29 but normally held out of action by a wire 22 which passes round a pulley 24 to a fixed point 23, and is arranged together with a spark gap 21 across the circuit. If the potential rises sufficiently, the current jumps the spark gap, and heats and thereby extends the wire 22 until the spring 29 can release the cut-out 15, 17.

Title: Process for Obtaining Sulphide of Zinc from Copper Slag Containing Zinc and Barium.
Inventor: BRUENJES FERDINAND
Filed: 1902-07-22
Granted: 1902-09-11
Abstract: 16,272. Br³njes, F. July 22. Barium chloride; zinc sulphide.-Finely-ground copper slag, containing zinc as oxide, and barium, calcium, and iron as sulphides, is treated with just sufficient dilute hydrochloric acid to cause the barium, calcium, and iron to pass into solution as chlorides. The zinc separates as sulphide during stirring, and the temperature rises to 120‹ C. The zinc sulphide is filtered off, washed, and dried. The solution is cooled, half of the barium chloride precipitating. The remainder of the barium chloride is obtained by evaporating the solution down to 39‹-40‹ BÚ. If zinc slag or a zincchloride lye is employed, barium and calcium sulphides are added, and the zinc sulphide then thrown out as before by adding hydrochloric acid.

Title: Improvements in Electrostatic Apparatus for Relay and other Recording and Operating purposes.
Inventor: RUNG GEORG ADOLPH
Filed: 1903-01-28
Granted: 1904-01-28
Abstract: 2112. Rung, G. A., and La Cour, D. Jan. 28. Barometers; thermometers; hygrometers. - Relates to apparatus for use in dew-point indicators, barographs, thermographs, and generally in delicate relays in which the motion of the leaves of an electroscope is caused to produce a closure or opening of an ordinary relay signalling or recording circuit or to produce a motion of a siphon-recorder pen directly. Fig 1 shows an arrangement in which the weak received currents can operate a relay a to control the charging of the leaf f of an electroscope by means of the high voltage source of electricity b. The leaf f carries a contact h capable of closing the contacts k of a local receiving- circuit. In Fig. 2, the relay lever W carries a proof plane x, by the motion of which the action of the outer plates q, r of the electroscope is accentuated, the middle pivoted plate being arranged to close the local circuit or to carry a siphon pen a<1>. In Fig. 3, the main line or relay is connected at 7, a high resistance 5 being bridged across the electroscope. In a further form, the charging and discharging of the electroscope is controlled by the motion of the relay in connection with a flame or source of radient energy. Instead of the relay as shown, an electrodynamometer, built as a delicate astatic galvanometer, may be employed. The high resistance used may be graphite streaks &c. or a capillary glass tube varnished outside and filled with alcohol, platinum terminals being fixed in each end. In determining the dew-points, the outer terminals of the electroscope circuit are brought into contact with the surface of the vessel containing the liquid. As soon as a film of dew is deposited, the charge of the electroscope is disturbed and a signal given.

Abstract: 10.006. Marks, G. C., [Soc. Romanet et Guilbert et Alphonse Guenet]. May 2. Incandescent vapour lamps.-In an inverted incandescent lamp, a horizontal tube 1 contains a wick 4 leaving a vaporizing-chamber 5 at the end. The supply of alcohol or other spirit from the reservoir 6 is controlled by a tube 8 screwed at the lower end and provided with a collar 12, the screwed part being partly flat, at the part 11, to allow spirit to pass when the collar is raised above its washer 13. The tube 8 also provides for the escape of vapour when the pressure becomes excessive. The vapour-supply tube 14 and the mixing-chamber 17 are bent so that the air inlets 15 are not in the path of the combustion products. The lamp is started by an auxiliary heater consisting of tow 25 supplied with spirit by a tube 26. After starting, a conducting-plate 24 assists in vaporizing the spirit in the chamber 5. In modifications, (1) the pipe 26, supplying the auxiliary heater, leads from a small reservoir connected to the main reservoir 6 by a two-way cock so that only the necessary quantity of alcohol can flow to the heater 25 ; (2) a perforated metal tube is buried in the wick to facilitate the flow of the spirit, and the cock 28 is dispensed with, the vapoursupply tube 14 being carried alongside the tube 1 so as to be heated by the heater 25 ; (3) the wick is formed of amianthus washers having V-shaped slots which coincide to form a vaporizing-passage, which can be fitted with one or more threads of amianthus. A tray surrounding the lower part of the burner is supplied with alcohol from the heater 25 and ensures a more rapid initial lighting.

Title: A Novel or Improved "Stamp" or Mandril for use in the Manufacture of Lap-welded Tubes.
Inventor: ROBINSON WILLIAM
Filed: 1904-07-28
Granted: 1905-06-01
Abstract: 16,611. Robinson, W. July 28. Welding.-In the manufacture of lap-welded tubes, a "stamp" or mandrel is used which may be readily taken to pieces if it becomes jammed in a partially-formed tube. The mandrel A is divided lengthways into a number of parts C, C<t>, which are slidable longitudinally on one another and which are held together in their normal positions by interlocking or dovetailed portions. A rod B, having a collar E which bears against the back of each of the parts C, C' supports the mandrel A. The heated skelps are drawn by rolls over the mandrel A and welded to form a tube, but, if the mandrel becomes jammed, the rod B may be removed and a bar placed against the backward projection F of a part C and struck by a hammer. The corresponding part C is thus driven forwards and then the other parts C are similarly treated. The parts C' will then be loose in the tube, and may be withdrawn and put together for further use. The parts G need not have back projections F: The mandrel, when worn, may be turned down for use in drawing a tube of smaller size.
